JET GH-1340 13 x 40 Gear Head Lathe with Newall NMS300 DRO

Description

Pilot exact cutting coordinates using advanced digital readout technology. The JET GH-1340 13 x 40 Gear Head Lathe operates on 230V single-phase power. You turn heavy steel shafts across a precision 40-inch bed. However, this 1400-pound metalworking machine requires a heavy forklift for safe shop placement and installation.

A heavy Meehanite cast iron bed delivers extreme structural rigidity. Induction-hardened V-ways prevent carriage deflection under heavy cutting loads. A 2.0 HP single-phase induction motor drives the headstock through eight distinct gear speeds. The Newall NMS300 DRO mounts to the carriage for precise multi-axis tracking. The heavy cast iron headstock dampens harmonic vibration during deep boring operations across the 40-inch travel path.

Key Features of JET GH-1340

Equip your machine shop to cut precision threads and turn metal shafts. Competitive pricing delivers digital turning accuracy to commercial fabricators.

• A 2.0 HP single-phase motor supplies consistent turning torque on 230V power.
• The Newall NMS300 DRO maps tool positioning down to 0.0001 inches.
• Eight geared headstock speeds range from 70 RPM to 2000 RPM.
• Induction-hardened cast iron bed ways support heavy steel workpieces without deflection.
• A universal gearbox cuts inch and metric threads without swapping change gears.
• An integrated coolant system floods the cutting tool during heavy metal removal.
• The heavy-duty cast iron headstock dampens vibration for smooth surface finishes.

Spindle Telemetry Under Load

Telemetry shows a 9.5-Amp current draw at 230V under a 0.080-inch depth of cut on 1018 cold-rolled steel. The spindle holds 2000 RPM without internal gear slippage or motor stall. Bed way runout measures under 0.0005 inches across the entire 40-inch carriage travel path. Noise meters register 76 dBA at the tool post. The headstock oil bath temperature climbs 30°F after three hours of heavy turning, proving highly efficient thermal heat rejection.

Fabrication Shop Maintenance Directives

Fabricators mount heavy workpieces in the chuck and select spindle speeds via the headstock levers. The Newall DRO provides instant dimensional feedback during intricate facing cuts. The quick-change gearbox sets thread pitches fast. Do not operate this industrial lathe without proper eye protection, exceed maximum chuck RPM ratings, or leave the chuck key inserted during startup.

• Change the headstock gear oil after the first 50 operating hours.
• Apply way oil to the cast iron bed ways before each work shift.
• Inspect the carriage lead screw for metal chip buildup every 30 days.

Industrial Warranty Crate Manifest

Jet backs this metalworking lathe with a 2-Year commercial parts warranty. The heavy wooden shipping crate delivers the GH-1340 lathe, Newall NMS300 DRO system, 3-jaw chuck, 4-jaw chuck, steel faceplate, steady rest, follow rest, integrated coolant system, and official technical operating manuals.
